Big Trucks = Big Bucks?
Most full-size pickups offer an off-road package, although these are generally limited to 1⁄2-ton models. The GM 1500HD and 2500/3500s, Ford SuperDutys, and likely the 2003 Ram HD have skidplates, limited-slips, and the occasional steering damper.

The Chevy Avalanche Z71 package (not on 2500s, standard on North Face edition) includes a limited-slip, 265/70-17s on alloy wheels, skidplates, high-capacity air filter, rubber floormats, and upgraded springs and shocks, for $835. A similar Z66 package, with traction control and self-leveling rear suspension, goes on 2WDs.

The Silverado/Sierra 1⁄2-tons both offer Z71 suspensions systems, often as part of an off-road package. To Z71 springs, shocks, and bump stops, add bigger tires, alloy wheels, aluminum skidplates, a larger air filter, and a removable air dam. At press time, these packages went for $275-$1050 because of special deals--at $275, we wouldn't think twice.

You can get a Tundra TRD Off-Road package for a 2WD or 4WD, and 30 percent of buyers choose it. It consists of 265/70-16 BFGoodrich tires on alloy wheels, Bilstein shocks, springs, foglights, mudguards, and fender flares (on 2WD) for $950. A limited-slip is $275, with no locker (as on Tacoma) available.
